We need to keep in mind that _metadata->exit_code can be KSFT_SKIP while the process exit code is 0. Cc: Jakub Kicinski Cc: Kees Cook Cc: Mark Brown Cc: Shuah Khan Cc: Will Drewry Reported-by: Sean Christopherson Tested-by: Sean Christopherson Closes: https://lore.kernel.org/r/ZjPelW6-AbtYvslu@google.com Fixes: 0710a1a73fb4 ("selftests/harness: Merge TEST_F_FORK() into TEST_F()") Signed-off-by: Mickaël Salaün Link: https://lore.kernel.org/r/20240511171445.904356-11-mic@digikod.net --- Changes since v5: * Update commit message as suggested by Sean. Changes since v4: * Check abort status when the grandchild exited. * Keep the _exit(0) calls because _metadata->exit_code is always checked. * Only set _metadata->exit_code to WEXITSTATUS() if it is not zero. Changes since v3: * New patch mainly from Sean Christopherson. --- tools/testing/selftests/kselftest_harness.h | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/tools/testing/selftests/kselftest_harness.h b/tools/testing/selftests/kselftest_harness.h index cbedb4a6cf7b..3c8f2965c285 100644 --- a/tools/testing/selftests/kselftest_harness.h +++ b/tools/testing/selftests/kselftest_harness.h @@ -462,9 +462,13 @@ static inline pid_t clone3_vfork(void) munmap(teardown, sizeof(*teardown)); \ if (self && fixture_name##_teardown_parent) \ munmap(self, sizeof(*self)); \ - if (!WIFEXITED(status) && WIFSIGNALED(status)) \ + if (WIFEXITED(status)) { \ + if (WEXITSTATUS(status)) \ + _metadata->exit_code = WEXITSTATUS(status); \ + } else if (WIFSIGNALED(status)) { \ /* Forward signal to __wait_for_test(). */ \ kill(getpid(), WTERMSIG(status)); \ + } \ __test_check_assert(_metadata); \ } \ static struct __test_metadata *_##fixture_name##_##test_name##_object; \
